Title: Improvements in the suction feeding of sheets, cards, collapsed cartons and the like
Inventor: ROSE ALFRED GERMAN
IPC: B65B43/24
Filed: 1949-09-16
Abstract: 686,103. Feeding sheets. ROSE BROS. (GAINSBOROUGH), Ltd. Aug. 31, 1950 [Sept. 16, 1949], No. 23866/49. Class 100 (i). Sheet - separators. - Collapsed cartons 12 stacked vertically on edge in a magazine 11 are separated from the stack by a suction head 13 which first moves substantially perpendicularly to the plane of the end carton to pull away the front edge, against the action of a spring-urged finger 39, and then moves substantially at right angles to pull the carton away from a fixed stop 41 and out of the magazine. A number of suction heads 13 having metal-faced suckers 27 therein are arranged around a rotatable central shaft 18, and comprise hollow arms 14 rotatablymounted in spider arms 16 fixed to the shaft 18 which is intermittently-rotated by a shaft 26 through a Geneva mechanism. Suction is applied to the suckers 27 through the arms 14 which are supported by a plate 29 over a fixed suction chamber 28. An inner wall 31 of the chamber 28 acts to cut-off the suction at a predetermined point. At their upper ends, the arms 14 have extensions 32 provided with rollers 33 engaging a cam groove 34 in a cam plate 36 freely mounted on the shaft 18 and arranged to be oscillated by a link 37 eccentrically-mounted on the shaft 26. When the shaft 18 is rotated, the leading approaching arm 14 is rocked inwardly by the cam 36 to clear the end carton 12, and then rocked outwardly to engage the carton. The shaft 18 now stops, the arm 14 is moved inwardly to withdraw the leading edge of the carton away from the stack, the shaft 18 is then rotated whereby the arm 14 moves substantially transversely of the stack to withdraw the carton from the stack against the action of the fixed stop 41, and carries it to a position where, on further outward movement of the arm 14, the leading edge passes into a recess 42 on a projection 43 from a guide rail 44. The shaft 18 again stops, the cam 36 causes the arm 14 to rock inwardly so that the carton is opened by an abutment 46 on the projection 43, and on further rotation of the shaft 18, the carton is collapsed in the opposite direction, assisted by a stop 47 on the arm 14, and led between the guide rails 44 where it is released by the suckers 27. A projection 48 on a chain conveyer 49 then feeds the carton forward to a carton-filling machine. When the suckers 27 engage the carton in the stack, they lie rearwardly of a score line on the carton which acts as an abutment for the suckers during separation of the carton from the stack. Specification 686,105, [Group XVII], is referred to.

Title: Improvements in and relating to the manufacture of water gas
IPC: C10J3/46
Filed: 1926-09-28
Abstract: 270,948. Bowater, N. J. Sept. 28, 1926. No Patent granted (Sealing fee not paid). Producers.-In producing water gas from pulverized fuel which is employed in both blow and run periods, the heat of combustion not stored in the generator lining during the blow period is imparted to the steam for the run and the sensible heat of the water gas and surplus steam is utilized for preheating air for combustion during the blow. To reduce the period of contact of the fuel with the reacting gases a higher temperature, e.g. 1250‹ C., is employed than that, e.g. 900‹ C., which would secure under equilibrium conditions the desired proportions of hydrogen and carbon monoxide. These are obtained by passing the fuel and gases at a faster rate through the generator or by employing excess steam which restricts the intimacy of contact. Air blown through an inlet F absorbs heat in a regenerator C from a previous run and is intimately mixed with fuel fed through an inlet D'. The mixture is admitted tangentially at the bottom of the generator A and further air and fuel may be introduced at inlets J to maintain turbulence. Or the cross-sectional area of the generator may gradually increase towards the top. Combustion products pass through a regenerator B and give up their remaining heat to a waste heat boiler W. For the run, steam is admitted though an inlet G and meets a stream of fuel from an inlet D, the gaseous current being influenced in the generator as during the blow period. The sensible heat of the water gas and surplus steam is taken up by the regenerator C and a waste heat boiler W<1>.

Abstract: 712,766. Processing microscopic specimens. BARNARD, H. F. Oct. 15, 1952 [Oct, 15, 1951], No, 23936/51. Class 97(1) [Also in Group XXIX] In an apparatus for processing tissue for microscopy, wherein the tissue is successively and automatically immersed in a series of processing liquids, means are provided for keeping the liquids hot, thus enabling the processing to be accomplished quickly. The time during which the tissues are immersed in the liquids and the movement from one liquid to the next may be controlled by a tipping bucket mechanism. As shown, the processing liquids are contained in six pots, 10, which are immersed in the water bath 12, kept hot by a thermostatically controlled electric heater 13. The bucket 19 is filled with water from the constant drip, 22 and when filled to a certain level, tips and empties its contents, returning to its original position under the action of the counter-weight 21. As the bucket tips, the shaft 20 makes one complete revolution and the hook 24 engages one of six pins 26, spaced on the spider wheel 25, thus raising the rod 14 and turning it through one sixth of a revolution at the same time. The tissues 17 are suspended from a wheel 15, secured to the rod 14, and thus the tipping of the bucket raises each tissue from a processing pot, moves it into position above the next pot and lowers it therein.
